--> I made a SmartHome project using NodeMCU and 4CH Relays... I am using IFTTT service to connect the Adafruit IO to my Google Assistant to give commands....

--> It works perfectly, and I can control the Relays either with Google Assistant or directly from https://io.adafruit.com on browser.

--> Since it is not very convenient to log into Adafruit IO to toggle the controls on and off, I went to the Playstore and searched for some 3rd party MQTT apps (since Adafruit IO doesn't have their own).

--> Problem was I couldn't connect to Adafruit MQTT Server, but I was successful in connecting to the same from other apps (from Playstore) and also could publish/receive, but wasn't working with this app (link above).

--> I entered the same credentials (same as the others apps that worked) and also checked with the API documentation, I tried with SSL connection too, but nothing seems to work with this app.

--> I suggest you to try the same and reply if you have the same problem/found the solution. For any further info, please leave a reply...........

Thanks a lot :)..............................

Clearly this is my first post, feel free to leave suggestions below......... :)

also i would like to share my settings/configs... you will be asked to enter these to connect.. (you can find these in the API Documentation also, but beware you'll probably loose interest xD) (and sorry for the image format, lol)
